Source Number Estimator In Pulse Train Data

Abstract

Data that consists of a number of superimposed pulse trains (each train having a simple pulse arrival pattern) is considered. The number of independent trains present is of interest in a number of applications. By considering the variance (over window position) of the number of pulses lying in a time window the number of periodic sources can be determined. This method of Cox and Smith is generalized from strictly periodic emitters to those with noise or periodic patterns.
